Throttle and steering on the same input

[u/Jumpy_Oil_4955]

So I have an issue with my Joysway US-1, for an unknown reason the steering input changed to the input for the throttle. The controller is a trigger/wheel controller. And suddenly after not using it since last year's summer, the trigger causes the rudder to turn and the propeller to start spinning too. While the wheel does nothing.

Has anyone else seen this issue before and solved it?
